P peterluolaw Unregistered / Unconfirmed GUEST, unregistred user! 2001-12-12 #1 请问各位大侠,如何判断一个BLOB学段的内容是否为空呢?我的窗体上只添加了 TDATASOURCE和TTABLE两个控件.
W whf Unregistered / Unconfirmed GUEST, unregistred user! 2001-12-12 #2 Table1.FieldByName('aa').IsNull
S savenight Unregistered / Unconfirmed GUEST, unregistred user! 2001-12-12 #3 Table1Graphic.IsNull 判断不就行了
